Gaudete ( or , ; "rejoice [ye]" in Latin) is a sacred Christmas carol, thought to have been composed in the 16th century. It was published in Piae Cantiones, a collection of Finnish/Swedish sacred songs published in 1582 in the North German city of Greifswald. No music is given for the verses, but the standard tune comes from older liturgical books. There is a known entry from around 1420 in the Hussite Jistebnice hymnal (Jistebnický kancionál).
